It was a hug fail worthy of a Seinfeld episode, and now Jerry Seinfeld himself is explaining what happened. "I'm 63, I don’t know every pop star," he tells Extra of an awkward encounter with Kesha in which he rebuffed her requests for a hug while he was doing a red-carpet interview (video of it here). "When you get to be my age and you've done a couple things, you have your own reality—in my reality… I don't hug a total stranger." No word on Kesha's side of things, but there are apparently no hard feelings. Seinfeld says they met later and laughed about it. "She was very nice about it." (More Jerry Seinfeld stories.)
